화학적 성질
Colorless transparent viscous liquid화학적 성질
4,4'-Methylenebis(2-methylcyclohexylamine) (MACM) is a colorless/yellowish liquid with a water solubility of 3.6 g/l at 20°C and a vapor pressure of 0.08 Pa at 20°C. The measured log KOW is 2.51 at 25 °C. However, due to the Lewis base character of the substance, the experimental determination of the log KOW is inaccurate. The density of the substance (ca. 0.95 g/cm3 at 20°C) is virtually the same as that of water.용도
4,4'-Methylenebis(2-methylcyclohexylamine) can be used as epoxy curing agents.일반 설명
4,4′-Methylenebis(2-methylcyclohexylamine) is an alicyclic diamine.위험도
Moderately toxic by inhalation.Safety Profile
Moderately toxic by inhalation.When heated to decomposition it emits toxic vapors ofNOx.Synthesis
Add 2000kg 3,3'-dimethyl-4,4'-diaminodiphenylmethane and 2000kg tetrahydrofuran to an autoclave with a volume of 6000L. Then, 100Kg 5% Ru/Al2O3 catalyst and 100Kg aluminum ammonium sulfate will be added, and the air in the autoclave will be replaced with hydrogen after sealing. Pour in 6MPa hydrogen, heat the autoclave to 160°C, adjust the hydrogen valve to maintain the pressure at 8MPa, and stir vigorously for 4 hours. After cooling, samples were taken and detected by gas chromatography-mass spectrometry. The detection results showed that the conversion rate of 3,3'-dimethyl-4,4-diaminodicyclohexylmethane was 100%, and the 4,4'-Methylenebis(2-methylcyclohexylamine) (MACM) yield was 99.4%.라로민 C 260 준비 용품 및 원자재
